Abstract

 Objective To study the influencing factors on anemia in preterm infants at the corrected age of 6-month-old based on gestational age (GA), birth weight (BW) and feeding patterns. Method Preterm infants with GA<37 weeks (n=124) were followed up to 6 months of corrected age (CA) between June 2014 and November 2015. The incidence of anemia in preterm infants among different groups according to GA, BW and feeding pattern was statistically analyzed. Results Preterm infants included are of 70 males and 54 females. Median age of GA was 33.7 weeks with an average BW of 1910g. The incidences of anemia was 30.6% (95% CI: 23%, 38%) in preterm infants at 6 months of CA, 66% in breast-fed preterm infants. which is significantly higher than 19% in those receiving mixed feeding and 13% in those receiving formula feeding (P=0.000). No significant differences in anemia incidence were found among preterm infants of different GA and BW. Conclusions Anemia incidence in 6-month-old preterm infants is associated with feeding pattern, which conferrs greatest risk. It is necessary to undergo further analysis and treatments for preterm infants with anemia.
